FREDERICK MUNSTER, OF MILL'VILLE, NEW JERSEY.

- RUDDER FOR BOATS AND SHIPS.

To all whom it may concern;

Be it known that I, FREDERICK lVIUNSTER, a citizen of the United States,residing at Millville, in the county of Cumberland and State of NewJersey, have invented certain new and useful Improvements in Rudders forBoats and Ships, of which the following is a specification.

My invention relates to improvements in rudders for boats and ships, theobject of the invention being to provide two rudders, which may beoperated for steering the boat, and which may be manipulated so as toposition the rudders in alinement, and at right angles to the line ofmovement of the boat, so as to act as a brake and retard the movement ofthe boat.

A further object is to provide improved means for independentlyoperating the rudders, and improved means for locking them together tocompel their simultaneous operation.

lVith these and other objects in view, the invention consists in certainnovel fea tures of construction, and combinations and arrangements ofparts as will be more fully hereinafter described and pointed out in theclaims.

In the accompanying drawings, Figure 1, is a plan View illustrating myimprovements applied to a small boat. Fig. 2, is v Fig. 3, is a view inlongitudinal section. Fig. 1, is an enlarged sectional plan view showingthe means for locking the two rudders together. Fig. 5, is adiagrammatic plan view illustrating a modification showing myimprovements as applied to a large ship. Fig. 6, is a diagrammatic viewin side elevation of Fig. 5. Fig. 7, is a diagrannnatic exaggerated planview of a portion of the device showing Figs. 5 and 6. rigs. 8, 9, 10and 11, are enlarged Views of details of the construction shown in Figs.5, 6 and 7.

Referring to the structure disclosed in Figs. 1, 2, 3 and 4:, showing myimprovements as applied to a small boat, 1 represents the boat having anoverhang portion 2 at its stern, in which a tubular shaft 3 is mountedto turn, and a solid shaft 4 is mounted to turn in the tubular shaft 3,and extends above and below the tubular shaft as shown most clearly inFig. 3. The tubular shaft 3 is provided with a collar 5 bearing on theoverhang portion 2 to limit Specification of Letters Patent.

Application filed. June 29, 1909.

Patented Mar. 22, 1910. Serial No. 504,967.

the downward movement of the shafts, and hand wheels 6 and i" aresecured upon the shafts 1 and respectively, the hand wheel 6 beingpreferably smaller than hand wheel 7. Rudders 8 and 9 are secured to thelower ends of shafts at and 3 respectively, and a notched wheel 10 issecured. to shaft it, and rests upon the upper face of hand wheel 7, anda pivoted dog 11 on hand wheel 7 is adapted to engage in any of thenotches of the wheel 10, and lock the shafts 3 and t together.

In the normal operation of the device when used for steering purposes,the shafts 3 and 4 are turned until their rudders S and 9 lie flattogether, when the dog 11 will be moved into one of the notches in wheel10. so that. the manipulation of either of the wheels (3 and 7, willserve to swing both rudders, and they will act as an ordinary rudder tosteer the boat.

hen it is desired to utilize the rudders to retard the speed of theboat, dog 11 is thrown off wheel 10, and wheels 6 and '7 are separatelyoperated to' throw the rudders 8 and 9 into alinement, and at rightangles to the direction of movement of the boat, and when the dog 11 isswung into locked. engagement with the wheel 10, these rudders will befirmly held in this position, and will retard the speed of the boat.

In providing large ships with my improvements, I preferably constructthe same as shown in Figs. 5, 6, 7, 8, 9, 10 and 11, in which the ship12 is illustrated in dotted lines, and the rudders 13 and 1 1 aresecured upon a solid shaft 15 and tubular shaft 16 respectively, andpulleys 17 and 18 are secured upon thesolid shaft 15 and tubular shaft16 respectively, and a bracket 19 provides a support for the upper endof the shaft, said bracket being secured upon a cross beam or deck plate20. At the bridge or pilot house wherever the steering is to be done, asolid shaft 21 is provided, and partly inclosed in a tubular shaft 22,steering wheels 23 and 24 being secured upon the upper end of solidshaft 21 and tubular shaft 22 respectively. Tubular shaft 22 has apulley 25 secured thereon, and solid shaft 21 has a pulley 26 securedthereon. An endless cable or other flexible connecting device 27 ispassed around and secured to pulleys 25 and 17, so that when tubularshaft 22 is turned by steering wheel 24, the rudder 13 will be moved. Asecond endless cable or such position.

flexible connecting device 28 is passed around and secured to pulleys 26and 18, so that when solid shaft 21 and steering Wheel 23 are turned,the rudder 14 will be moved.

To limit the turning movement of the rudders l3 and 14, :1 lug 29 isprovided on tubular shaft 16 and engages stops 30 on plate 20, so as toallow the rudder 14: but a quarter turn. In other words, moving from aposition in line with the path of movement of the boat to a position atright angles to such line of movement, a similar lug 31 is secured tothe upper end of solid shaft 15, and engages stops 32 on bracket 19 tolimit the turning movement of rudder 13.

In ordinary operation, one rudder is always stationary, and in line withthe path of movement of the shaft, while the other rudder is turning tosteer the ship, and as one rudder is turned to guide the ship to oneside or the other, the rudder which had formerly been out of line, willswing back to To swing both rudders to a position at right angles to thepath of movement of the ship, so as to retard the forward movement ofthe ship, a cylinder 33 is provided, connected by a steam pipe 34 withthe engine room, and the passage of steam through said pipe to becontrolled by the engineer upon signal from the pilot house. Thiscylinder 33 contains a piston 35 connected by a rod 36, said rod 36pivotally connected to a cross rod 37, and the latter connected byclamps 38 with the cables 27 and 28 respectively, so that when thepiston 35 is forced forward by the steam, both of these cables will bemoved, so as to draw the rudders to a position at right augles to themovement of the ship, and hold them in such position against the actionof the water, thus acting as a brake to quickly stop the vessel. Owingto the pivotal connection between rods 36 and 37, the cables arepermitted free independent movement in ordinary steering and are onlysimultaneously moved when it is desired to quickly stop the vessel.

Various other changes might be made in the general form and arrangementsof parts described without departing from my invention, and hence I donot restrict myself to the precise details set forth, but considermyself at liberty to make such changes and alterations as fairly fallwithin the spirit and scope of the claims.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is:

1. In combination with a boat, a tubular shaft, and a solid shaft withinthe tubular shaft and projecting above and below the tubular shaft, of arudder secured to the lower end of the tubular shaft, a second ruddersecured to the lower end of the solid shaft, means permittingindependent movement of said shafts, said means also permittingsimultaneous movement of the shafts to position the rudders at rightangles to the line of movement of the boat, and means independent of thefirst mentioned means for holding the rudders in this position at rightangles to the movement of the ship.

2. In combination with a boat, two vertical shafts at the stern of theboat, and a rudder on each shaft, two steering shafts, steering wheelson said shafts, pulleys on all of said shafts, endless cables connectingthe pulley on one steering shaft with the pulley 011 one rudder shaft,and another endless cable connecting the pulley on the other steeringshaft with the pulley on the other rudder shaft, means for limiting theturning movement of said steering shaft, a cylinder, a piston in saidcylinder, a cross rod pivotally connected to said piston rod and securedatits ends to said cables respectively, and means for conveyingexpansive fluid to said cylinder to simultaneously move said cables,substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

FRED. MUNSTER.
